Lake plain grill, HF control gear & Emergency, IP65, 28w 2D

Mains and Emergency eyelid bulkhead fitting with additional front security
grill.
The Lake is a low energy premium quality surface mounted bulkhead with a tough anti
vandal main body and an eyelid to reduce light pollution and direct glare. It is
suitable for both internal and external use and as a commercial or domestic applications
and finished in the traditional textured powder coat.
The lake can be either ceiling or wall mounted.

High frequency control gear means instant start from the lamp and longer lamp lifeThe
energy efficient 2D 4pin 28w lamp is included
and produces 2,050 lumens of light and even with the opal polycarbonate
diffuser it is bright enough for stairways and a main source of building
perimeter lighting.

It has integral maintained 3 hour emergency control gear.

Lamp colour ( Kelvins )

Lamp colour is determined by the Kelvins and a lamp which is 2,700 kelvins
is classed as warm white and is sympathetic to skin tones and warm brickwork. A lamp
with a kelvin of 6500 is in the cold blueish white spectrum and works well
against a white background and will appear brighter to the naked eye than the warmer
colour spectrum.

Light output ( Lumen's )

All lamps have a lumen number and the higher the lumen number the
brighter the lamp,
however colour of the lamp (kelvins ) also comes in to play here as a
whiter lamp
at 6,000 kelvins and above would always appear brighter to the naked
eye than a warmer
colour lamp at the 2,700 kelvins light spectrum even if it has the
same lumen output.
A halogen 150w R7 lamp that is used in a standard garden security
flood light would
produce around 2,300 lumen's and a 26w compact fluorescent would
produce around 1,800 lumen's. Placing lights closer to the item to be
illuminated is a good way of
using a lower lumen lamp rather than trying to flood light a big
area.

Environmental impact

Care should be taken for the environment and local wildlife to maintain the ecological
balance. Insects, bats, wildlife can all be effected by light pollution. The
warmer colour spectrum of ( 2,700 Kelvins ) does not interfere with insects
and general wildlife as much as the blue colour spectrum of light around 6,000 kelvins
which can disrupt their normal night time activity. This also applies to bats where
a anti glare light fittings works better as well as reducing the overall light pollution
in the area. You must also be mindful of your neighbors and the effect your lighting
can have on them and shining a 500w tungsten halogen flood light in to their windows
at night will cause them distress. Try to keep the light in a downward position and
local to the items you want to illuminate and even if you want to illuminate tall
trees it can be done in a sympathetic way by placing a ground buried or surface spike
flood light directly under the trees to illuminate the canopy. Some light fittings
also have a anti glare shield fitted to reduce light pollution.

IP Rating

All the luminaries on our web site have been specifically designed fit for purpose
and assigned a relevant IP rating which denotes the amount of protection that is
required from water and dust. More information on IP ratings can be found in the
design ideas section on this web site.

Light levels ( LUX )

Light levels are measured in something called LUX. Put simply LUX is a measurement
of light falling on a given surface area. For example an average LUX of 200 would
be needed for an outdoor tennis court for recreational purposes and a side street
walkway would have an average of 5 LUX. To calculate lux levels you need a
very good calculator or computer as there is a number of factors that need to be
taken in to account.
